Specification

The 1756-ON8 from Allen-Bradley is a high-performance digital input module designed for the ControlLogix platform. It provides eight isolated input channels, each configurable for either sinking or sourcing DC signals, making it ideal for monitoring discrete sensors, limit switches, and pushbuttons in manufacturing lines. With robust isolation and fast response times, this module ensures reliable data acquisition even in electrically noisy environments. Its hot-swappable design allows for module replacement without powering down the chassis, maximizing system uptime. Backed by Rockwell Automation's rigorous quality standards, the 1756-ON8 is a trusted solution for both new installations and legacy system upgrades.
